Title: Wire reinforced vascular prosthesis
Inventor: CHARLES TOMONTO
IPC: A61F2/90
Filed: 1999-02-18
Abstract: What is described herein is a endovascular tube or bifurcated prosthesis used for the repair of aneurysms or other vessel disease. This can be soft or hard occlusive disease. This prosthesis is constructed by fabricating a structure that consists of a textile or other polymeric material and through which is threaded a superelastic metal wire such as a nitinol, a ductile wire or other filament material. The textile can be a polymeric material. The wire provides the self-expandability of the current device. Ideally, the thickness of the device should be minimized, so that it can be delivered to the diseased site using a percutaneous procedure.

Abstract: A surgical apparatus is described for performing cardiac surgery on the coronary organs of a patient. It has a contacting means capable of providing a mechanical load on at least a portion of said coronary organ, a positioning means which allows the setting of either or both the contacting means and coronary organ in a large number of positions or orientations within a surgical workspace. The apparatus also has a manipulation means serving as a single point control to position and orient the contacting means onto the coronary organ tissue. An adjustment means serves to bias the range of at least one motion degree of freedom of the surgical apparatus within a the limits of a restricted range that is less than the full range of motion of that degree of freedom of motion that would be otherwise achievable when the bias is not present or overridden. This achieves the placement of the contacting means within the surgical workspace, with or without the simultaneous manipulation, retraction, or stabilization of coronary organ tissue also within the workspace. Any of the motion degrees of freedom of the surgical apparatus can be "biased". All motion degrees of freedom of the surgical apparatus are linked, 'whether biased or unbiased, through the manipulation means which the surgeon utilizes to set the contacting means or coronary organ tissue.

Title: Apparatus and method for scheduled playing of compact disc audio tracks
Inventor: JOHNSON ROBERT HENRY
IPC: G11B27/11
Filed: 1998-01-14
Abstract: An apparatus and method of scheduling audio tracks on audio compact discs in a CD jukebox to be played at predetermined times is disclosed. The method includes storing, in a CD audio track index location on an audio CD, a value indicating that the audio CD is a sequence CD containing audio tracks that are to be played at predetermined times. The stored value also specifies a predetermined sequence, or schedule to use with the sequence CD. A controller computer (108), within the CD jukebox and external to the CD player, utilizes CD-DA commands to query (118) the CD player for the CD audio track index (120) on each audio CD. The responses are used to distinguish normal audio CDs from sequence CDs. A periodic interrupt invokes a sequence interrupt handler that determines whether any audio tracks on any sequence CDs are scheduled to be played. If one or more audio tracks are scheduled (122) to be played, the CD slot number and audio track number are inserted at the front of a queue of selections to be played, causing the newly-entered selections to be played after a presently-playing audio track completes.

Inventor: KIKUCHI YOSHIAKI
IPC: B60L11/18
Filed: 1999-08-30
Abstract: The temperature of a battery in a hybrid car is supervised by temperature sensors. When the temperature of the battery is at a temperature not exceeding a predetermined temperature, a battery ECU issues a command to a control CPU to perform forcible charge/discharge of the battery to raise the temperature of the battery. When raising of the temperature is performed by charging, a requested output from an engine is increased as compared with a usual state. In such a state, motor-generators are operated as generators so as to generate electric power and charge the battery by passing an electric current to the battery rather than generating a driving force. When raising of the temperature is performed by discharging, the requested output from the engine is reduced as compared with the usual state. In this case, the motor-generators are operated as drive motors to consume electric power so as to draw electric current from the battery causing discharge of the battery. The electric current allowed to flow at. this time causes internal resistance to be generated in the battery that heats the battery from an inside portion thereof. Thus, an apparatus for controlling a charge/discharge state of a hybrid car can be provided that quickly and easily controls the temperature of the battery to a predetermined temperature.
